G'day. My first post here, and I truly hope I've come to the right place.

I've been scanning a box, and it's - lightly taken - set up very
insecure. Many open ports, etc. One thing I find strange is the
following: The box is open on port 80. But if you telnet into it, it
doesn't act anything like a HTTP daemon.

#1. If you connect to it, it waits for remote input.
#2. It accepts a certain number of chars before it closes the connection.
#3. If you immediately send the max. number of chars, (or more) the
connection is closed at once.
#4. You can send five times an 'a', and then get disconnected.
#5. If you'd send 'abc', you'll get disconnected after < 5 times
(usually 3 or 2)
#6. Every time you send something, (except doing #3) it returns some
ASCII that seems to be different everytime. (even if you keep sending
the same)

So .. what do you think I'm looking at? A trojan or something?
Guessing on its open ports I believe it's a WinME OEM, Win2000 or
(probably) WinXP box. (UPNP enabled)

I'm eager to notify its user, but I first really want to know what that
port 80 deamon is :)
